We have developed the Trusted RV which is a combination of 4 core 64bit RISC-V (namely, AC: Application Core) and 1 core 32bit RISC-V Secure Coprocessor (namely, SU: Secure Unit). The AC runs Keystone as Trusted Execution Environment and the SU works as a "Root of Trust" to keep and process critical information (e.g., Device Key, Certificate). The Trusted RV is implemented on an FPGA (Xilinx VC707) and a simulator. To make a Trusted Application (TA) on the Trusted RV, we offer a programing and management environment. We developed a library for GlobalPlatform TEE internal APIs on Keystone. The communication from the AC to the SU is limited for Keystone's Enclave only and keeps security. A TA is managed by TEEP (Trusted Execution Environment Provisioning) and can be installed/updated/deleted from a server securely. In this talk, we explain the total secure implementation of TEE.
